SPECIFICATION forming part of Letters Patent No. 746,332, dated December8, 1903. Application led July 29,1903. Serial No. 167.381. (No model.)

,I construct, and use my invention, I will proceed to describe it,referring to the drawings herewith, in which- 'l Figure 1 shows a bottleand closing-cap in longitudinal section with the stopper being l zoforced to place beneath the upper surface of the cap through a. centralopening thereof by means of a bottle-filling apparatus. Fig. 2 shows asimilar view in whichthe stopper has been forced toits place beneath theupper sur- 2 5 face of the cap.

A is the body of the bottle. B is a circumferential'bead near the top ofthe4 neck of the bottle.

C is acircumferential groove formed be- 3o beneath bead B.

B is the top surface of the cap. B2 is a circumferential drop-flange toB. B3 is an ear vor indent in ange B2, which takes under the bead B ingroove C to hold the cap against removal by pressure from within thebottle. There are two or more of these ears or indents in said fiangeB2, (gen- E F GH J are details of a bottling-machine' pressing thestopper in taper tube H of the 6o Vc'orking-machine to a size which willpermit it to pass through said openingD and beneath it, as shown in Fig.2. The stopper thenexpands to its original size, thus filling thebottle-neck, andthe outward pressure of the l gases and liquid in thebottle forces the stopper upward against the under side of the topsurface B of the cap and against the walls of the bottle-neck and sealsthe bottle against leakage. The greater the pressure in the bot- 7o tlethe tighter will be the sealing.'

Having owfully described myinvention and the manner in which I haveembodied it, what I claim as new and as my invention, and desire tosecure by Letters Patent, is 75 In a means for sealing vesselscontaining liquids under pressure, the combination consisting of avessel provided with a neck and means to receive a cap; a sealing-capprovided with means for securing it, over the mouth of said vessel-necksaid cap having a. substantially flat upper surface, and a centralopening in said top surface of less diameter than the inner diameter ofthe vesselneck; and a stopper entered beneath the top Witnesses:
